Milk is rich in nutrition. Many people drink milk before breakfast and sleep at night. I think it will help them sleep and make them sleep more stable and comfortable. But some people say you can't drink milk on an empty stomach. Is there any scientific basis for this statement? How on earth should we drink milk? Milk is the standard breakfast for many people, but drinking milk as soon as you get up in the morning is harmful to your health. Drinking milk on an empty stomach not only affects digestion, but also causes nutrient loss. What harm will it do?

1, affecting digestion

Because water accounts for a large proportion in milk, drinking more milk on an empty stomach dilutes gastric juice, which is not conducive to the digestion and absorption of food. In addition, on an empty stomach, the intestinal peristalsis is very fast, the speed of milk passing through the gastrointestinal tract is very fast, and the retention time is also very short. Its nutrition is often too late to be absorbed, so it rushes into the large intestine and goes through the motions. Therefore, drinking milk on an empty stomach is not in line with nutrition and hygiene.

2, produce harmful substances

If you drink milk on an empty stomach, not only will the milk be discharged from your stomach quickly, but also the high-quality protein will be decomposed by your body and consumed as heat, which will not give full play to the due role of protein. Some amino acids are excreted into the large intestine before being absorbed by the small intestine. In the large intestine, these protein and amino acids are decomposed into substances harmful to human body, which increases the burden on human body.

3. Damage to the stomach

Many people eat milk and eggs for breakfast and drink milk directly after washing their faces. Drinking milk on an empty stomach will make the stomach too late to digest, the nutrition of milk can not be absorbed by the stomach, and even flatulence may occur. At the same time, hyperacidity leads to protein's degeneration and precipitation, and nutrients are not easily absorbed by the stomach, which can lead to severe indigestion and diarrhea. Therefore, try to drink milk after meals, which is conducive to absorption and tolerance.

4, leading to nutrient loss

The reason why we can't drink milk on an empty stomach at breakfast is that after a night's sleep and rest, our stomachs have already been emptied and we are fully prepared to eat and digest food. Therefore, the stomach empties quickly at this time, and milk is liquid milk food. After drinking, it is discharged into the intestine before it is fully digested and absorbed in the stomach, which greatly causes the loss and waste of nutrients.
